Ventilating shoe pad

ABSTRACT

A ventilating shoe pad includes a pad body made of plenty of elastic fiber that is loosely and separately interwound together, with numerous gaps formed among the interwound fiber. The pad body is formed by thermal compression with a protective edge slightly extending upward obliquely at the peripheral edge corresponding to the recessed portion and the heel of a user&#39;s foot. The ventilating shoe pad of this invention has good permeability and good elasticity, safe and comfortable in using.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a ventilating shoe pad, particularly to one having good elastic buffering effect and good permeability.

2. Description of the Prior Art

Formerly, shoes, such straw sandals and clogs, are simple in structure, but their insoles that contact with a user's feet are comparatively hard without good elasticity. Later, shoe pads have been designed and used for improving the above-mentioned drawback. A conventional shoe pad, as shown in FIG. 1, is made of foam plastic or leather or synthetic leather to be fitted on the insole of a shoe for thickening the sole of the shoe or reinforcing treading elasticity so as to prevent a user's feet from being hurt.

However, most of the conventional shoe pads can hardly have both good permeability and elastic buffering effect. For instance, a shoe pad 1 shown in FIG. 1 made of foam plastic has good elasticity but lacks good permeability, while a shoe pad made of leather or synthetic leather with a close structure has not good elasticity and is worse than the foam-plastic shoe pad 1 in permeability. Such shoe pads with poor permeability cannot produce air convection between the sole of a user's feet and the insole; therefore, it is likely to produce stinking smell inside the shoe and make the user sweat on the sole of the foot to wet the interior of the shoes and gather mold therein, liable to cause skin diseases on a user's feet.

SUMMARY OF THE INVENTION

The objective of the invention is to offer a ventilating shoe pad including a pad body made of plenty of elastic fiber that is loosely and separately interwound together, with numerous gaps formed among the interwound silk. The pad body is thermal-compression formed with a protective edge slightly extending upward obliquely at the peripheral edge corresponding to the recessed portion and the heel of a foot. The ventilating shoe pad of the present invention has good elastic buffering effect and good permeability, safe and comfortable in using and able to keep feet dry to avoid causing skin diseases.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A first preferred embodiment of a ventilating shoe pad 3 in the present invention, as shown in FIGS. 2 and 3, includes a pad body 10 and a cushion 20 combined together.

The pad body 10 is made of plenty of elastic fiber 11 made from plastic materials, such as PVC, PP or PE. The elastic silk 11 is loosely and separately interwound together, with numerous gaps 12 formed among the interwound silk 11. Further, the pad body 10 is formed by thermal compression with a protective edge 13 slightly extending upward obliquely at the peripheral edge corresponding to the recessed portion and the heel of a user's foot.

The cushion 20 is made of knitted fabric, having its shape and size approximately matching with those of the pad body 10. The cushion 20 is glued on the pad body 10 with adhesive for a user's foot to step thereon.

In a process of making ventilating shoe pads of the invention, an integral-sheeted cushion 20 and an integral-sheeted pad body 10 can be glued together in advance and then, according to the interior space shape of a shoe, cut into many half-finished shoe pads. Next, the half-finished shoe pad has the peripheral edge of the pad body 10 formed by thermal compression with a protective edge 13.

Referring to FIGS. 3 and 5, since the pad body 10 of the ventilating shoe pad 3 of this invention is made of plenty elastic fiber 11 with proper elasticity and the elastic silk 11 is loosely and separately interwound into an elastic structure; therefore, when a user step on the ventilating shoe pads 3, he will feel safe and comfortable due to the elasticity and the buffering action of the pad body 10. In addition, the protective edge 13 slightly extending upward obliquely at the peripheral edge corresponding to the recessed portion and the heel of a user's foot enables the pad body 10 and the cushion 20 glued thereon to keep close contact with the outline of a user's foot and also has functions of embellishment and protection. Moreover, the pad body 10 is formed with numerous gaps 12 so the whole shoe pad 3 has excellent permeability, able to keep feet dry to avoid sweating and skin diseases.

A second preferred embodiment of a ventilating shoe pad in the present invention, as shown in FIG. 6, has the same structure as that described in the first preferred embodiment, except that the cushion 20 is punched with plenty of air holes 21 matching with the numerous gaps 12 of the pad body 10 so as to enhance permeability of the shoe pad 3.

While the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
